Step What to do How to do it
1 Make sure the
controller is
configured for
Auxiliary Output and
the proper range (4
to 20 or 0 to 20) is
configured.
Make Options set up group function prompt Auxiliary
Output any selection other than Disable.If this prompt
does not show up, check if DIG IN 2 is enabled. If so,
then as Auxiliary Ouptut and Digital Input 2 are mutually

Make the Options Set UP group function prompt CO
Range = 4–20 or 0–20 per your application.
See Configuration for more information.
2 Check the field
wiring.
Output impedance must be less than or equal to 1000
ohms.
3 Check the output. Change the Auxiliary Output selection to Output.Put
the controller into Manual mode and change the output
from 0 % to 100 % (4-20 mA). Use a DC milliammeter
at the rear terminals to verify the output.
4 Recalibrate the
